    • Q:

      I purchased this item one year ago. It came with two batteries. One of the batteries will not take a charge. The other works fine. My local Home Depot does not carry the 36volt lithium battery anymore. What should I do?

    New Vs. Reconditioned

    Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.

    • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
    • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
    • Both come with a manufacturer warranty and are covered by our Money Back Guarantee;
      New is 30 days, Reconditioned is 60 days.
